I don't know if territory captures the entirety of the meaning. There's a notion of culture and tradition that isn't captured by the kinda geographic meaning of territory

It seems like it's a bit like "home soil" which has cultural connotations.

I can't think of an exact single word in English for the translation but I imagine every large country has the concept of regional cuisines and farming traditions feeding into a regional identity

British people often point out that other languages don't really have a word for "fair play" but it's not like these cultures don't understand and respect the importance of integrity, respect, justice etc.

In general this don't-have-a-word-for thing is massively overplayed (hygge probably the worst example). We're all the same species of ape.

Id say the word "regional" is a closer fit to capturing the original meaning.
